Abstract

Implantable infusion apparatus (10) includes a housing (14, 16) with an inlet passage (22) extending into the housing at a pronounced promontory (18) on the housing wall. The passage has an outer end at the top of the promontory and an inner end defined by a needle stop (124) positioned inside the housing. Self-sealing septa (134, 144) mounted in the passage at selected spacings from the needle stop divide the passage into a plurality of aligned inlet ports (136, 154) each of which has its own fluid outlet (132, 149). One of the outlets (132) leads to a pumpable infusate reservoir (46) having an outlet conduit (76) connected to a catheter (24) that extends outside the housing; another (149) leads directly to the outlet conduit (83) so that while a first fluid is being pumped from the reservoir to the catheter, a second fluid can be introduced into the other inlet port for mixing with the first fluid flowing to the catheter. Several different infusate flow configurations are also disclosed.
